How PSTN-To-VoIP Calls Work

ATA Administration Guide

98

PSTN-To-VoIP calls can be made with two-stage dialing only. The only 
authentication method available is the PIN method.

The ATA device takes the FXO port off hook after a configurable number of rings. If 
PIN Authentication is enabled, it prompts the caller to enter the PIN number 
followed by a # key. The Inter-PIN-digit timeout is set at 10 seconds. Up to eight 
PSTN PIN numbers can be configured in the ATA device. If the given PIN does not 
match any of the PSTN PIN values, the ATA device plays the reorder tone to the 
FXO port for up to 10 seconds, and then takes the FXO port on-hook. If the given 
PIN matches one of PSTN PIN values, the ATA device plays dial tone to the FXO 
port and is ready to accept digits for the target VoIP number from the PSTN caller. 
The collected digits are processed by the dial plan associated with the PIN 
number.

If Authentication is disabled, a default dial plan is used for all PSTN callers.
